Formation of oat fresh yield and its protein yield in the conditions of the southern forest-steppe of Western Siberia

The results of the study grain and fodder oat varieties in competitive variety trial Omsk Agrarian Research Center are dis-cussed. article provides data on green food yield its protein for period from 2018 to 2020. samples were tested under conditions with contrasting moisture content. Physiological indices vari-eties also analyzed: leaf area, accumulation distribution dry bi-omass as well percentage protein. response by year different weather is shown. A favorable has been identified formation a common assimilating area plants. It was revealed that content vegetative mass oats varies oppositely total yield. biomass onto-genesis characterizes photosynthetic activity positive relationship their yieldability. selection begins SP-2 nursery.
